Description
SYSTEM AND METHOD FOR JOB MANAGEMENT
TECHNICAL FIELD The present invention relates to a job management and more particularly to a system and method for job management system in grid computing connecting grid portal with a plurality of job scheduler.
BACKGROUND ART
Grid computing or grid portal is a mechanism for managing heterogenous a set of computing elements, operating systems, policy decisions and environments. A long term vision of enterprise grid computing community may be non-dedicated and interoperability of various disparate systems, wherein the various disparate systems being part of similar organization or various organizations. Grid computing may be looked upon by various experts as technology whereby the technology may potentially change the way people administrate and interact.
Traditionally, grid portal architecture involves web browser, grid portal, and job scheduler. The 3 tiers system represents physical and administrative boundaries between the grid user, the Grid Portal and the scheduler. The grid portal is a web based user interface to access grid resources via web browser over a network. Current practice, the grid portal is developed using browser-supported language such as HTML, JSP, Java, JavaScript and etc. The Grid Portal services include the following:
i) job submission wherein executing step-by-step job submission to the grid resources ii) job monitoring wherein online monitoring of submitted jobs with running, waiting or queuing status. Users have the option to view output file online, as well as terminate and restart running jobs.
iii) job reports wherein online view of completed, terminated or restarted jobs, enabling users to view and download output files and restart terminated jobs.
Grid portal services have a lot of advantages wherein it includes automotive repetitive tasks of scheduling multi-step processing, increase job success rate through a guided step-by-step job submission, hides the complexity, by reducing the leaning curve of using the grid applications through the command line interface and provide online monitoring of job status anytime and anywhere, by enabling fast decision making in order to terminate problematic jobs and restart with new elements. Job scheduler is a resource management system comprises of at least one resource management server and a plurality of resource agent components or devices. The resource agent devices are suitably configured to receive the jobs or tasks scheduled by the resource management server and subsequently execute the assigned jobs. One of the many significant tasks of in relation to resource management involving a plurality of computing resources is to provide effectual scheduling of predefined tasks among these computing resources over a network. The scheduling is principally configured to perform job scheduling for resources on a larger scale, or as mentioned, between multiple computing resources. This particular task therefore
entails additional vital tasks such as monitoring the plurality of computer resources and serves as the primary entry point for any jobs or tasks submission.
The current portal architecture and implementation is tightly coupled with job scheduler. The portal communicates with the job scheduler by using application programming interfaces (API) provided by the job scheduler. However, there are lots of drawbacks from this method as the grid portal is tightly coupled with the job scheduler and must be in-line with the scheduler API evolution. In order for a grid portal to support multiple job schedulers, the grid portal has to take care of supporting multiple API call to the job scheduler. This normally causes problems of maintaining the grid portal if the job scheduler is evolved. There is also the unavailability of generic or standard job management system which mapped the API call to job scheduler. Patent number US20050262506 and US6438553 have disclosed system and method related to job management service. However, comparing the present invention and the prior arts, these publications have not disclosed any of job management system that intermediately connects the grid portal and the job schedulers which is more feasible and reliable, particularly in managing plurality of job schedulers for job submission and monitoring process.
Therefore, there exists a need for a job management system that may be able to handle a plurality of job schedulers at the same time without interrupting the whole process of job submission and monitoring.
